我在'A7-A5'表格上有输入

如何将输入输入到以下列表中: [['A',7],['A',5]]

我正试图(根据需要)杀死目前正在运行的所有python进程.
我正在使用此命令:

from subprocess import call  
call('pkill python', shell=True)  
print 'Killed them all!'

但是,当然 - 我的程序也是一个python程序,所以最终,它在调用'call'后没有到达打印行.

我可以做些什么来避免我的程序同时杀死自己,同时杀死所有其他python进程？
谢谢.

当我尝试编译这个程序时,我在第21行得到一个"无法访问的语句"错误:

import java.util.*;
import java.io.*;
import java.nio.file.*;
import java.lang.StringBuilder;

class FilePrep {
    public static void main(String args[]) {
    }
    public String getStringFromBuffer() {
        try {
            Path file = Paths.get("testfile2.txt");
            FileInputStream fstream = new FileInputStream("testfile2.txt");
            BufferedReader br = new BufferedReader(new InputStreamReader(fstream));  
                String inputLine = null;                    
            StringBuffer theText = new StringBuffer();  

            while((inputLine=br.readLine())!=null) {
                theText.append(inputLine+" ");
            }
            return theText.toString();
            System.out.println(theText); // <-- line 21
        }
        catch (Exception e)
        {
            System.err.println("Error: " + e.getMessage());
            return null;
        }
    }
}

完整的编译器输出是:

Main.java:21: error: …

是

char buf[] = "test";

在C相当于

String buf = new String("test");

在Java？

并且是

char *buf;
buf = "test";

相当于

String buf = "test";

？

如何在Windows XP上使用youtube dl下载youtube视频.有任何命令吗？我想将这个工具与PHP集成.请帮忙..

我希望代码在php示例中通过2个单词得到2个单词:

stackoverflow the best site of asking

结果:

2 words : stackoverflow the
2 words : best site
2 words : of asking

我是python和Pyramid的新手.我今天安装了金字塔,我已经在我的mac机器上预装了python 2.7.1.我已经按照官方网站上提到的说明安装了金字塔.我已经在网站上提到了virtualenv和nositepackages,我在我的/users/sreekanth 目录中安装了金字塔

安装后,我尝试了我的第一个示例程序,如文档中所述.

当我尝试运行该程序时,我收到的错误如下所示.
